纳入标准:

1.受试者和/或其监护人须在试验前对本研究知情同意,并自愿签署书面的知情同意书,并愿意按照试验所规定的时间点进行随访; 2.能在监护人帮助下与研究者进行良好的沟通并遵守研究者的要求。对于无成熟语言能力的幼儿,能在监护人帮助下配合并遵守研究者的要求; 3.受试者和/或监护人对本试验有正确的认识,对获益有适当的期许; 4.年龄>=6个月,性别不限; 5.根据基因检测报告显示为GJB2突变所致耳聋患者:GJB2纯合或复合杂合突变; 6.听力学入选标准:重度及以上耳聋(>=65 dB) 7.满足耳科手术要求:如3个月内或筛查时通过CT扫描和/或MRI扫描排除如严重的中-内耳畸形、蜗神经发育异常等;并确认是否满足手术资格。

Inclusion criteria

1.The subject and/or their legal guardian must provide informed consent prior to participation, voluntarily sign the written informed consent form, and be willing to comply with all scheduled follow-up visits; 2. Ability to communicate effectively with the investigator with the assistance of a guardian and adhere to study requirements.

Other types of hearing loss unsuitable for the specified otologic surgery, such as severe middle-inner ear malformations or cochlear nerveabnormalities identified on CT/MRI within 3 months; 3. Pre-existing otologic conditions that would impede the planned surgery or interfere with endpoint interpretation (e.g., acute/chronic otitis media, Ménière's disease, acoustic neuroma, unresolved sudden sensorineural hearing loss); 4. History of drug abuse; treatment with any known ototoxic medications within 6 months (e.g., aminoglycosides, cisplatin, loop diuretics); or receipt of antiviral/immunotherapy within 3 months; 5.Severely immunocompromised individuals, history of significant immunodeficiency (including HIV positivity, other acquired/congenital immunodeficiency diseases), or history of organ transplantation; 6. Severe systemic diseases or acute conditions (e.g., tuberculosis, active hepatitis B/C, active herpes zoster infection, pancreatitis, renal insufficiency, gastrointestinal ulcer); 7. Contraindications to surgery/anesthesia as determined by the surgeon, anesthesiologist, or designee (e.g., cerebrovascular accident, myocardial infarction, heart failure, angina, transient ischemic attack within past 6 months; hypersensitivity to planned medications); 8. Presence of implants in the operative ear at screening (e.g., cochlear implant); 9. Coexisting other severe congenital disorders; 10. History of significant neurological or psychiatric disorders (e.g., epilepsy, dementia) not adequately controlled; 11. Any other condition deemed by the investigator to make the subject unsuitable for participation.
